Location Approximation Using Channel State Information Based Pre-Coding in a Massive MIMO Scenario

Abstract

The objective of this study is to investigate, in a pure MIMO scenario, how the ability of the system to determine the location of the user is affected when the number of antennas surpasses the number of users. With the increase in the number of antennas, the multi-user MIMO becomes a massive MIMO scenario. In this study, the established pre-coding matrices for different users will be used to determine the location of a user in a line-of-sight, or Rician, channel set-up with random non line-of-sight elements. The localization approximation will be a matter of comparing the closeness of the pre-coding matrix from the transmission to the actual user channel matrix. Zero-forcing is used to establish the matrix necessary to determine the location of users in multiple grid sizes for one, two, and five users.
